I was out markign the loop for this weekends coming race and in some sections it was quite fast and some was quite sandy... when I would click a gear up and get on it, it felt like it had a 5 second delay before it got up and going...I couldnt pin point if it was slipping or if it was delayed shifting. It also sometimes goes to neutral when shifting downwards towards first and I am hard on the lever so I know it is going down all the way, for example some tight 2nd gear trail comes to a base of a hillclimb and I jam it in 1st and the thing goes to neutral and pisses me off! Any ideas? The bike has under 1000 miles on it but that is a lot of slow speed,over revving, coolant spitting, technical nasty stuff. Oil has been changed twice since new...15-50 mobil 1.
